Gently scrape away the outer polyimide insulation layer on the COF tape using a micro-blade to expose the bare copper underneath.
For those requiring the in PDF format with full timing diagrams, we recommend filing a technical request with the original LCD manufacturer using the panel model number found in Section 5.3. nt61219hc6021a cof datasheet exclusive
By soldering a microscopic jumper wire from the T-Con board directly to the missing voltage pin on the NT61219HC6021A

Generally requires ACF (Anisotropic Conductive Film) bonding machinery for replacement.
: Uses a microchip mounted directly onto a flexible film substrate with fine-pitch copper wiring (often as fine as 35 µm). Key Specifications & Applications By soldering a microscopic jumper wire from the
The remains a highly specialized, exclusive component within the repair ecosystem. Its full technical datasheet is rarely found online, making it a source of frustration for hobbyists and a guarded secret for professionals.
High-grade insulated copper jumper wire (typically 0.02mm diameter). A high-magnification stereomicroscope. UV-curable insulating solder-mask resin. Step-by-Step Jumper Procedure
: Resources like Scribd and technical repair forums provide aggregated lists of COF voltages and pinouts.
The NT61219HC6021A COF is suitable for a wide range of display applications, including:
